Application filed June 21, 1920. Serial No. 390,514.

To all whom it may concern:

Be it known that we, GRANVILLE A. HUMAsoN and JULIUs A. BUn'rsoHEL, citi zens of the United States, residin at Houston, in the county of Harris and tate of Texas, have invented a certain new and useful Improvement in a Pump, of which the following is a specification.

This invention relates to new and useful improvements in a pump, specially designed for use in deep wells, such as oil wells, and has more particular relation to a novel construction of the working plunger thereof.

One object of the invention is to provide a pump, having a plunger constructed with novel means of packing which is carried by said plunger and interposed between it and the working barrel, and which will prevent the leakage of fluid past between said plunger and barrel.

Another object is to provide, in a pump,

a plunger which will be very durable so that it will not have to be often renewed.

A further feature consists in the provision of means whereby steam, air or similar fluids, under pressure, may be utilized to assist in lifting the fluid, to be pumped, from the well.

A still further feature resides in an improved form of valve seat employed.

With the above and other objects in view the invention has particular relation to certain novel features of construction, opera-v tion and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 is a vertical sectional view of one form of plunger employed, shown in its relation to the standing valve.

Fig. 2 is a side elevation thereof.

Fig. 8 is a transverse sectional view taken on the line 33 of Fig. 1.

Fig. 4 is a transverse sectional view taken on the line 4L-4 of Fig. 1.

I Fig. 5 shows a bottom end view.

Fig. 6 shows a fragmentary vertical sectional view of a modified form of plunger.

Fig. 7 shows a transverse sectional view taken on the line 7-7 of Fig. 6.

Fig. 8 shows an enlarged fragmentary sectional view of the valve seat.

Fig. 9 shows a vertical sectional View of an her f rm at a p drawings, wherein like numerals of reference designate similar parts in each the numeral 1 designates the valve casing whose upper end is reduced forming the neck 2, which is outwardly threadedfto receive the lower end of'the tubing 3 which extends up through the bore to the ground surface. The lower end of this neck has a valve seat 4 threaded therein, having a fluid passage way '5 therethrough, controlled by of the figures @Ft'iti sectional view the valve 6 thereabove. This valve has "the upstanding stem 7 which works through a [central bearing in the spider 8 which is anchored in the neck 2, and surrounding this stem and interposed between said valve and spider there is a coil spring 9 which nor-, mally holds the valve seated.

The numeral 10 designates a long tubular nipple whose upper end is formed into an enlarged outwardly threaded head llwhich is screwed into the lower end of the valve casing 1. The upper end of this head is formed into .a double valve seat 12 which is controlled by the valve 13, located above the seat. The under side of this valve is convex so as to seat perfectly on the. seat 12. This seat is formed with two annular shoulders,

12 above and 12"beneath it and between said' shoulders there is an annular groove provided to receive the packing ring 14. VVhen' theshoulder 12 wears too much to form a close fitting seat for the valve, said valve will then seat on the shoulder 12 which with the packing ring 14 will form a perfect seat for said valve to past said seat. a g V The valve 13 has an upstanding stem 15, which has radiating guides 16 adjacentthe valve which prevent the wabbling of the valve and cause a true reciprocation thereof, up and down. The upper end of the stem prevent leakage of the fluid has a transverse slot 17 a extending passageway 21 is restricted forming an annular shoulder 23and within the passageway there is a coil spring '24 which 'isseated on this shoulder and whose outerend supports a ball valve 25 which is held, by said spring agains'tthe inner end-of the seat 22. v Surrounding the nipple 10 are the sectional rings 26, arranged in pairs which are separated by the continuous rings 27, also arranged in pairs. The adiaeentendsot the sections of the rings 26 have registering recessesin which are located the coil springs 28 and the inner side or" each section has a recess, which registers Fwith an opposing recess inthe periphery ofthenipple 1G and in :these respective recessesare the pressure springs 29, said springs 28 and 29 serving to cause the rings 26 to expand in all directions uniformly. pic 10 and located betweenthemeinbers of each pair of continuous rings 27 are the annular packing gaskets30 which prevent any leakage between the nipple .andits surrounding rings. p

Surrounding the rings 26 and 2'? there are the expansible split relatively wide, bands 31 arranged adjacent and whose adjoiningedges have tongue-and-groove joints. The upper band. abuts agalnstthe lower end of the casing l and interposed between them is p the packing ring 32 which is seated in an an.-

nular groove in the casing. An extended collar 33 isthreaded onto the'lower end of the nipple and its upper end abuts against the lower band 31 andlnterposed between them i is the packing ring 3% which is seated in an annular groove in the upper end of said sleeve. The periphery of each sectional ring 26 is grooved to. receive the surrounding packing rings 35 .interposedbetween theni and the opposing bands 31. A relatively wide packer element 36. formed "of loathe]; or other similar material surrounds the plunger and is seatedfin a dove-tailed groove in adjoining bands 31. and this element:

works closely against the working barrel 37 to prevent any leakage between the working barrel and plunger. The "sleeve hasa transverseslot 38 cut through one side thereof and a pin 39 is threaded into the lower end of the nipple 10 and. projects out'through said slot.

In asseniblingthedevice the valves of the casing I1 arefirst niounted "therein and the Surrounding the nip rings 26 and 2 are then slipped onto the nipple 10 from beneath. i; suitable surrounding clamp-sleeve is thenfitted around said rings toclamp theincloselyaround the nipple. The slee e 33 is then screwed onto the lower end of the nipple tightly against the rings to clamp them between the upper end ell said sleeve and the head 11 so as to prevent stand lugs ll provided to seat in opposing notches l2 in the lower end of the sleeve It is to be noted that the nipple 10 is connected to the valve casing 1 by means of right hand threads and thesleeve-3B is connected to'the nipple 10 by means of left hand threads. When the notches 42 are seated over the lugs -l-l the working barrelis then. turned to partially unscrew the nipple 10 from the sleeve the slot 38 and pin 39 permitting this but preventing the detachment ot said sleeve, and the 'expandiiig rings 26 will thus be released and will expand forcing the bands 31 out aga inst theworking barrel.

In the form shown in Fig. tithe seat 43 is ung thein are the bands, as 31, and

these rings and bands are assembled in the same manner as those of theforrn shown in In the form F g; l, hereinbe-fore describet or plunger now being considered the lower end of the reduced neck 2 is enlarged form ing a head 45 whichis threaded intoflthe upper end of the valve casing l. The undersi'de of 'thishead has" an annular groove 426 leading from which, upwardly through the head, are the passageways d7, d7. ll ithin the casing 1 there is an annular shoulder 48 and. resting on this there is a coil spring ll) which supports a ringlike valve 50 whose upper face is of a contour to seat in the groove d6 where itis normally held seated bythe spring d9, to closethe passageways 47. The upper end of the casing 1 is formed to present a sharp cutting edge 51 which scrapes the inside of the workingbarrel, within which it fits',"to keep said barrel cleansed and to prevent sedimentor other foreign matter iiroin working in between said barrel and plunger.

1e nipple'lO and lie adjacent and Upon up stroke this fluid is forced up through the tubing '3, through whichtheplunger is operated, to the top of the ground and additional fluid is drawn into the working barrel through the standing valve 40.

sure fluid will usually be steam or air. In

case the valves become clogged for any reason a cleansing fluid such as hot steam, gasolene or the like may be forced down into the chamber 20 to wash out and remove the offending substance.

In the form shown in Figs. 9 to 15, inclusive the valve casing 52 has its upper end reduced forming the neck 53 to which the lower end of the tubular sucker rod 54 is attached and whose lower end is normally closed by the back pressure valve 55. The lower end of the valve casing 52 has a valve seat 56 secured therein and controlled by the inlet valve 57. The lower end of the neck 53 also has radiating discharge ports 60. Threaded onto the lower end of the casing 53 is the nipple 61 whose upper end has the under-cut annular shoulder 62 and threaded onto the lower end of this nipple, by means of left hand threads, there is the extended sleeve 63 whose upper end is flared, said sleeve containing the seat 64 controlled by the inlet valve 65. The sleeve 63 has the slot 38 to receive the pin 39 which is threaded into the nipple 61 for a purpose hereinbefore explained.

Surrounding the center of. this nipple is the pair of outwardly taking spacer rings 66, 66 joined together by a tongue-andgroove joint and having the packing gasket 67 between them and the nipple. These spacer rings are confined between the expanding rings 68 and the packing gaskets 69 are arranged between them. Above and below these respective expanding rings 68 are the pairs of bands 70, 70 whose joints are broken by the annular packer elements 71, 71 which are seated in annular peripheral grooves cut in said bands. Between the expandin ring 66, 66 and the bands 70, 70, are the packing gaskets 72, 72. Above and below the respective bands 70 are the jointed rings 78, 78 which abut against the respective wedge shaped rings 74, 74 formed to conform to the adjacent under cut shoulder 62 and flared end of the sleeve 63. These elements surrounding the nipple 61 are assembled in a manner similar to that hereinbefore explained.

As the plunger is reciprocated fluid is admitted through the valve 65 and passes through the valve 57 is discharged throughtheports 59 and 60 and passes on up around the sucker rod 54 to the groundsurface. 1 Air or steam may be forced under pres sure down throughithe sucker rod 54 by the valve 55 and into the chamber 75 of the valve casing 52, which will pass thence through the ports 59 and 60 and assist in liftingthe oil or other fluid being pumped. For "cleansing the valves hot steam, gasolene or other cleanser may be in like manner forced down through saidrod 54 into the valve casing and its valves thereby cleansed. The fluid passing up through the working barrel 37, will be discharged out through the discharge pipe 76, which is controlled by suitable outlet valve 77. In case additional fluid pressure is required to assist in discharging the fluid through the pipe 76, as in case where the fluid is to be delivered into a tank or other receptacle, at a considerable distance from the well, air or steam may be forced under pressure through the line 78, which is connected into the top of the easing, and which is controlled by the inlet valve 79. j V

The forms of plunger hereinabove described, are very eflective in preventing the pump from becoming clogged, by means of sand or other sediment, which may settle around the standing valve 40, or which may collect in the working barrel, underneath the plunger. .In case the pump should be come clogged, pressure fluid, such as air or steam, is forced down through the working barrel and into the chamber '20, and up through the tubing 3, in the form shown in Figs. 1 to 8, inclusive, or it is forced down through the sucker rod 54 into the chamber 75, and back up through the working barrel, in the form shown in Figs. 9 to 15, inclusive, thus discharging the oil above the plunger, and the oil underneath will then flow through the plunger and carry up the settled sand or sediment with it, and thereafter as the plunger is reciprocated, said sediments will be carried up and out, thus relieving the pump of all clogging matter.

That we claim is 1. In a pump, a plunger including an elongated nipple, expansible sectional packing rings surrounding the nipple, resilient members interposed between the sections, and also between said sections and the nipple, spacer rings between said sectional rings and means for confining said rings on the nipple.

2. In a pump, a plunger including an elon- 3.
